I am Professor of Mathematics at Queensland University of Technology. Formerly, I held positions as an Australian Research Council Future Fellow (2014-2018) and as an Australian Research Council Postdoctoral Research Fellow (2006-2009). In 2012 I was awarded the JH Michell Medal for excellence in research by ANZIAM (Australian and New Zealand Industrial and Applied Mathematics), a division of the Australian Mathematical Society. In 2020 I was awarded the EO Tuck for outstanding research and distinguished service by ANZIAM.

I am Editor-in-Chief of the Bulletin of Mathematical Biology, which is the main publication associated with the Society for Mathematical Biology . The Bulletin of Mathematical Biology is devoted to publishing research at the interface of the life and mathematical sciences. Journal updates are published here .

Our recent work on understanding tumour spheroid growth has been highlighed in Technology Networks . In 2021 I was interviewed by Cosmos Magazine about mathematical biology, and the future of mathematical biology. The Random Sample podcast from 2020 provides some background on my research and how I came to work in mathematical biology. My QUT Research Snapshot summarises the aims of my research group.


My early research interests included using continuum mathematical models to interpret in vivo experiments in developmental biology focusing on neural crest cell migration. More recent projects involved developing stochastic mathematical models of these kinds of in vivo experiments and understanding how to construct approximate continuum limit descriptions of such stochastic models. More recently, I have been working at the interface of mathematical modelling, uncertainty quantification, parameter estimation and identifiability analysis. In general, my work involves deploying mathematical tools to understand various biological and biophysical applications that include studying tissue growth on 3D-printed scaffolds, in vitro observations of cell migration and proliferation using fluorescent cell cycle labels, as well as tumour spheroid experiments.


During 2019-2020, I was the Deputy Director of the Australian Mathematical Sciences Institute, and from 2016-2018 I was a member of the Australian Research Council's College of Experts, sitting on the Mathematics, Physics, Chemistry and Earth Sciences panel.

I am a member of the editorial board of Mathematical Medicine and Biology, and Physica D: Nonlinear Phenomena.


My most recent teaching interests include first year calculus and differential equations for engineering students, and later year courses on differential equations and computational modelling for mathematics students.
